Hi neks! I just want to simulate a laminar flow case like a Poiseuille flow. What case example I can use? Sorry for the question, I'm very new at nek. Thanks. Mateus. -- Mateus Peixoto Avanci Engenheiro Mecânico Aluno do Programa de Pós-Graduação em Engenharia Mecânica Universidade Federal Fluminense *http://lattes.cnpq.br/1773896725783894 <http://lattes.cnpq.br/1773896725783894>*
You can start with the nek example : helix. Make necessary modifications to helix.usr and helix.rea as needed. On Sun, Nov 20, 2016 at 10:12 AM, <[email protected]> wrote:

Helix example is a 3D Poiseiulle flow with flow in the z direction. I want to simulate a plane Poiseuille flow, in which a fluid is moving laterally between two plates whose length and width is much greater than the distance separating them. I don't know how to modify helix for my case. Can you help me? 2016-11-20 15:23 GMT-02:00 <[email protected]>:

Ok, if you are looking for plane-poiseuille flow you can look into the turbChannel example. It is designed for turbulent channel flow, but you can reduce the Reynolds number to generate a desired 3D Laminar flow. Also it is periodic boundary conditions, you can modify BC's like inflow/outflow according to your wish. Best Regards, Tanmoy On Tue, Nov 22, 2016 at 12:34 PM, <[email protected]> wrote:
